To all whom may concern: i i

Be it known that we, Gunnison H. How-` Ano and HARRY M. Prinsen, citizens of the Y United States, residing at St. Louis, Missouri, have invented a certain new an useful Improvement-in Truck Construction, of which the following is a full, clear, and exact description, such as will enable others skilled in the art vto which it appertains 'to make and the rigid and flexible equalizin reference being had to the acuse the same Y for-ming part of this companying drawings, specification, in which-s Figure 1 is a top view rillustrating one form of our improved truck construction. Fig. 2 is aside view partly in section and showing contained parts ini ,dotted lines` Fig. 8 is a detail in section on line 3-3 of Fig. 2. Fig. 4 is a detail 411-4 of 2. Fig. 5 isan enlarged horizontal section taken approximately on line 5-5 of Fig. 2. Fig. 6 is a detail section showing a modiiied arrangement of mounting the rigid equalizing members 'on the truck frame. Fig. 7 is a, cross sectional view of a built up wheel piece ladapted to receive members. Our invention relates genera ly to railway truck construction and more particularly to the construction of truck and the arrangement of the equalzing members with respect to the truck frame. In car construction, and particularly those cars utilized for the transportation of passengers, the distance from the is limited; and

I and between the wheels to carry` the sprA upon which the truck frame rests. Thus t e e%ualizing bars are necessarily of consider-V a le 'length so as to reach from journal to` journal and they must be of considerablesize in order to c the requisite strength.

Because of their sire and the position in which they are placed, the brake heads, the brake beams, vand other parte carried thereby, which are disposed inside the true are i l to a considerable ext/ent covered up are' such shape so as to in section on line' frame wheel pieces.

the truck frame to the) .therefore inaccessible for inspection or re.

pairs. v

It is the purpose of our invention to .construct a truck so arra ed that the inside brake shoes and heads willhe readily acces-- sible. for repairs or inspection` and with this -in view, we have constructed the Wheel piece of the truck frame substantiallyxhollow or of receive t e equalizing in embers, thus getting the equalizing mechanism in without materially raising the top of the .frame and utilizi the space between of frame and cross olsters, which has heretofore not been utilized. By virtue of our improved construction, we. are enabled to materially shorten the rigid ualilzing membersV and make' them both` li ter and stronger. Moreover, we are enabl to dispose the ualizing members so that they are entirely the truck frame where, if broken, they are not likely to fall on tothe track and cause derailment of the ear. Furthermore, in our improved construction, we are enabl d to utilize halfselliptc springs in place of .the halfscoiled springs now usually employed and thereby secure a. more liexible and easy acting suspensionof the truck; frame characteristic of elliptic springs as contrasted to coiled springs.

As illustrated in the drawings, our invention' is shown as applied to a six-wheel truck, but it is obvious that our invention is not limited to une on six-wheel trucks, butma'yi be employed en `truclnil having other casting, 'and com isos wheel tially channel shape throughout their len h with the exception of rtions that are kin posed from the iourn boxes and these p0rtions are substantiullybox shape in cross section. i .1"

The wheel pieces 5 are subst contained within The truck I is formed ina-sin'glc` the channelsliape of `the wheel ieces iininediately'over lthe bolsters 8 an between the portions of the wheel pieces over the journal boxes.A lAt the portionswhicli are pieces are provided with integral front walls disposed over the journal boxes, the wheel or rwebs 10, shown in Fig. 3, and these l the 'ournal boxes v9 or walls or- Webs4 materially reinforce the wheel pices immediately-over the journal boxes and at the points of attachment of the pedestal jaws,y The bottom flange of the wheel piece is cut away at the center of each box-shaped portion in order `to ac` commodate the vertical movement of the journalbox and the equalizer spring resting thereupon. Thepedestal jaws-.11 are secured in any suitable manner'to the walls or webs 10 and to'the bottom'llange of the wheel piece to the sides of the journal box opening in said bottom flange and the lower extremities of said jaws are-united by` a suitable tie strap. The truck bolsters'S of suitable construction are carried in the usual manner upon elliptical springs .14, which latter are carried upon the usual spring plank supported from the truck frame by hangers 15. The center beam or bolster 16 is carried by the truck holsters and in turn sup'portsthe centerbearing 17. Within the outwardly opening portion of each wheel piece 5, or those portions between the portions which are box shape in cross section, are arranged rigid equalizing bars 18 whichl are referably fulcrumed at 19. ,As shown in Fig. 2, each equalizing bar is provided 4with a single ulcrum, although, if desired, a double fulcrum, as shown` in Fig. 6, may be utilized. The ends of the equalizing bars V18 rest upon or are connected to the end portions of half elliptic s rin s yt e w eel pieces and the ends of said equal izing bars are provided with rounded bearing facesand depending lugs .18L whichl engage the end portions of said springs. The springs 20aremounted directly upon ugon bearing blocksl carried by said journal oxes, said springs 'supporting the weight of the truckframe and parts carried thereby. The ends of springs 20fatthe extremities of wheel pieces are en aged by links 21, the same being arranger? within and pivoted to the wheel pieces. l v,

f y By our improved construction, the wheel `pieces .and arrangement of the equalizing members therein, the brake heads 22 seen in dotted lines in Fig. 2, and other parts withinthe truck are in plain sight from thev side of the truck so that they within the truck may removed. lIt will also be seen that theV spected and the brake shoes ory other parts ,be readily applied or equalizing members eomprisin the -b rs 18 and springs 20 are centaine Vcomp etely eqnalizing 20 which are also disposed withinmay be readily in? within the hollow wheel pieces ofthe truck frame and thus if any'` ofv said members should. become broken, they will in allv probability be retainedn-the hollow wheel.

pieces and -thus be prevented from dropping on to the track. l y .By our improved construction, it is a comparativelyeasy matter to assemble the members and to replace or repair the same if necessary; At the extremities of the wheel pieces, the channel shape is maintained but the position o f the vertical web or wall isy reversed with respect to the channel shapled portions of the wheel pieces betweent e journal boxes; that'is, said vertif cal wall. or web is positioned on the outside with the horizontally disposed flanges projecting inwardly. Thisarrangement is clearly shown in Fig. 5. Ouiimproved arrangement of parts secures axilexible and universal equalization between the different pairs of wheels by virtueof the pivotal engagement of the truclctrame with the equalizing bars, for if anyI one" of the wheels l is raised or lowered relative to the others, the equalizing bars 18 willbe rocked on their fulcrums so as toI maintain an equal distribution of the weight u on all of the wheels. By thus increasing t e flexibilit ofthe truck, the riding movement of t e car is made'inore easy and gentle and by arranging the equalizing members within the hollow wheel pieces, the entire lower portion of thetruck is free and open to inspection or repairs and at the same time the entire structure'is well within the scope of the limited distance from the rails to the top of the truck frame or to theunder side of the car bod 'Wye havel shown and described a truck frame including the wheel pieces as being cast in a single piece, but it will be readily understood that a builtup structure hav? ing hollow wheel pieces may be constructed and-in Fig. 7 we have shown a hollow wheel piece'com osed of top and bottoniV members a prefere lyv in the fornirof channelsand connected to the webs thereof are verticallydisposed lates b, one of which inay be cut awa to orm openingsto permit inspection v of t e equalizing members.

We are aware that arrangements of the .parts other than those shown may be made vwithout departing from the spirit of our invention 'and it is intended that the scope of o ur invention as set forth in the agpended claims shall be construed to, inclu e all obvious 'changes and arrangements.
